Species-specific regulation of XIST by the JPX/FTX orthologs

X chromosome inactivation (XCI) is an essential process, yet it initiates with remarkable diversity in various mammalian species. XIST, the main trigger of XCI, is controlled in the mouse by an interplay of lncRNA genes (LRGs), some of which evolved concom ...

Energy-harnessing problem solving of primordial life: Modeling the emergence of catalytic host-nested parasite life cycles

Christian Iseli

All life forms on earth ultimately descended from a primordial population dubbed the last universal common ancestor or LUCA via Darwinian evolution. Extant living systems share two salient functional features, a metabolism extracting and transforming energ ...

SLC25A51 is a mammalian mitochondrial NAD(+) transporter

Kai Johnsson, Liang Wang

Mitochondria require nicotinamide adenine dinucleotide (NAD(+)) to carry out the fundamental processes that fuel respiration and mediate cellular energy transduction. Mitochondrial NAD(+) transporters have been identified in yeast and plants(1,2), but thei ...

DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Sonia Verp, Andrea Coluccio, Alberto De Iaco

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Mechanisms Underlying the Neuromodulation of Spinal Circuits for Correcting Gait and Balance Deficits after Spinal Cord Injury

Silvestro Micera, Grégoire Courtine, Eduardo Martin Moraud, Marco Capogrosso, Nikolaus Wenger, Emanuele Formento

Epidural electrical stimulation of lumbar segments facilitates standing and walking in animal models and humans with spinal cord injury. However, the mechanisms through which this neuromodulation therapy engages spinal circuits remain enigmatic. Using comp ...

Polycomb Recruitment and Targeting in Mammals

Patrick Schorderet

Polycomb- (PcG) and trithorax (trxG) group proteins are essential components in the regulation of multiple developmental regulators. In particular, during early stages, they act as chromatin modifiers in such a way as to set and maintain the transcriptiona ...

Embryonic stem cell potency fluctuates with endogenous retrovirus activity

Didier Trono, Helen Mary Rowe

Embryonic stem (ES) cells are derived from blastocyst-stage embryos and are thought to be functionally equivalent to the inner cell mass, which lacks the ability to produce all extraembryonic tissues. Here we identify a rare transient cell population withi ...

Rapid induction of functional and morphological continuity between severed ends of mammalian or earthworm myelinated axons

Jeffrey Alan Hubbell

The inability to rapidly restore the loss of function that results from severance (cutting or crushing) of PNS and CNS axons is a severe clinical problem. As a novel strategy to help alleviate this problem, we have developed in vitro procedures using Ca2+- ...
